Description

Technical Field

[0001] This utility model relates to the technical field of steel structure cutting equipment, specifically a cutting machine for steel structure processing. Background Technology

[0002] Steel structures are mainly composed of steel beams, steel pipes, and steel trusses. Steel structures have the characteristics of high strength, light weight, good toughness, and high reliability. When producing and processing steel structures, it is usually necessary to perform operations such as forging, welding, and cutting of steel.

[0003] During the processing of steel pipes, they need to be cut to a specified length. At this time, it is necessary to manually measure the dimensions on the steel workpiece and draw scale lines, and then align the blade on the cutting machine with the scale lines to cut. The manual drawing method leads to low cutting efficiency, which reduces the processing progress of the steel workpiece. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a cutting machine for steel structure processing.

A support rod is provided at the output end of the first motor. A second motor is fixedly installed at one end of the support rod. A drive wheel is provided at the output end of the second motor.

[0009] Two support components are symmetrically arranged on the upper end of the processing table. Each support component includes a base plate and a support shaft. Multiple fixed seats are fixedly arranged on the upper end of the base plate. A support rod is provided on the upper end of each fixed seat. A positioning frame is fixedly arranged on the upper end of each support rod. Both ends of the support shaft are rotatably connected to the positioning frame.

[0010] To provide a buffer when placing the steel pipe, the present invention includes the following improvements: the fixed base has an internal cavity with a spring inside; the support rod is inserted into the cavity and connected to the top of the spring; a second support frame is fixedly mounted on the upper end of the base plate; a third screw is rotatably mounted on the second support frame; a U-shaped limiting rod is provided on one side of the second support frame, which is penetrated by the third screw; the U-shaped limiting rod is threadedly connected to the third screw; and both ends of the U-shaped limiting rod can penetrate the fixed base and limit the position of the support rod.

[0011] To facilitate the adjustment of the base plate's position, the present invention includes the following improvements: two symmetrical sliding grooves are arranged on the processing table; a slider that slides in cooperation with the sliding grooves is provided at the lower end of the base plate; a first support frame is fixedly provided at the lower end of the processing table; a rotating shaft is rotatably arranged on the first support frame; two second screws with positive and negative threads are symmetrically arranged on the rotating shaft; the two second screws can pass through the slider respectively; and the second screws are threadedly connected to the slider.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a cutting machine for steel structure processing, which has the following advantages:

[0017] Rotating the first screw causes the threaded structure to slide the baffle on the processing table, aligning the pointer with the designated scale line. The baffle's position is fixed at this point. Since the laser cutting head is located at one end of the scale line, it's easy to determine the cutting length of the subsequent steel pipe workpiece. Starting the second motor rotates the drive wheel, which in turn causes the steel pipe workpiece to rotate at a constant speed on the two support shafts. Activating the lifting device lowers the laser cutting head to the designated height. Once the laser cutting head is activated, it can perform laser cutting on the rotating steel pipe workpiece. This process eliminates the need for manual marking on the workpiece, resulting in higher cutting efficiency and improved processing progress. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model discloses a cutting machine for steel structure processing, including a processing table 1. Multiple scale lines 2 are symmetrically arranged on the upper end of the processing table 1. A baffle 3 is slidably arranged between two scale lines 2. Two pointers 26 aligned with the scale lines 2 are symmetrically arranged on the bottom end of the baffle 3. A support base 5 is fixedly arranged at the rear end of the processing table 1. A first screw 6 is provided on the support base 5 and rotatably connected to the baffle 3. The first screw 6 is threadedly connected to the support base 5.

[0026] A lifting device 7 is fixedly installed above the processing table 1. A laser cutting head 8 is provided at the output end of the lifting device 7. The laser cutting head 8 is located at the front end of the scale line 2. A first motor 9 is fixedly installed on one side of the lifting device 7. A support rod 10 is provided at the output end of the first motor 9. A second motor 11 is fixedly installed at one end of the support rod 10. A drive wheel 12 is provided at the output end of the second motor 11.

[0027] Two support components are symmetrically arranged on the upper end of the processing table 1. The support components include a base plate 13 and a support shaft 17. Multiple fixed seats 14 are fixedly arranged on the upper end of the base plate 13. A support rod 15 is provided on the upper end of the fixed seat 14. A positioning frame 16 is fixedly arranged on the upper end of the support rod 15. The two ends of the support shaft 17 are rotatably connected to the positioning frame 16.

[0028] In this embodiment, the steel pipe workpiece to be cut is placed on two support shafts 17. The first screw 6 is rotated, and the threaded structure causes the first screw 6 to slide the baffle 3 on the processing table 1, aligning the pointer 26 with the designated scale line 2. At this time, the position of the baffle 3 is fixed. The steel pipe workpiece is further pushed so that one end of the workpiece contacts the baffle 3. Since the laser cutting head 8 is located at the front end of the scale line 2, it is convenient to determine the length of the subsequent steel pipe workpiece to be cut. Then, the first motor 9 is started, causing the support rod 10 to drive the second motor 11 to rotate, so that the drive wheel 12 contacts the steel pipe workpiece. The outer wall of the drive wheel 12 (with its own anti-slip sleeve) is activated by the second motor 11, which causes the drive wheel 12 to rotate. This allows the drive wheel 12 to drive the steel pipe workpiece to rotate at a constant speed on the two support shafts 17. The lifting device 7 is then activated, causing the laser cutting head 8 to descend to the specified height. Once the laser cutting head 8 is activated, it can perform laser cutting on the rotating steel pipe workpiece. The laser cutting head 8 is a common structure in the field of laser cutting, and it will not be described in detail here. This process does not require manual drawing of lines on the steel pipe workpiece, resulting in higher cutting efficiency and thus improving the processing progress of the steel pipe workpiece.

[0029] When the steel pipe workpiece is placed, a large impact force is generated between it and the support shaft 17, which can easily damage the support shaft 17. The fixed seat 14 has an internal cavity, and a spring 25 is installed inside the cavity. The support rod 15 is inserted into the cavity and connected to the top of the spring 25. A second support frame 23 is fixedly installed on the upper end of the base plate 13. A third screw 24 is rotatably installed on the second support frame 23. A U-shaped limiting rod is provided on one side of the second support frame 23, which is penetrated by the third screw 24. The U-shaped limiting rod is threadedly connected to the third screw 24. The two ends of the limiting rod can pass through the fixed seat 14 and limit the support rod 15. When the steel pipe workpiece is placed, the support rod 15 will compress the spring 25. Since there is frictional damping between the support rod 15 and the fixed seat 14, it can provide a buffer effect when the steel pipe workpiece is placed, so that the support shaft 17 is not easily damaged. After the steel pipe workpiece is placed, the designated third screw 24 is rotated. Through the action of the thread structure, the U-shaped limiting rod can move along the third screw 24, and the two ends of the U-shaped limiting rod can limit the support rod 15, thereby improving the stability of the steel pipe workpiece after placement.

[0030] In this embodiment, two sliding grooves 18 are symmetrically arranged on the processing table 1. The lower end of the base plate 13 is provided with a slider 19 that slides in cooperation with the sliding grooves 18. A first support frame 20 is fixedly arranged at the lower end of the processing table 1. A rotating shaft 21 is rotatably arranged on the first support frame 20. Two second screws 22 with positive and negative threads are symmetrically arranged on the rotating shaft 21. The two second screws 22 can pass through the sliders 19 respectively. The second screws 22 are threadedly connected to the sliders 19. By rotating the rotating shaft 21, the two sliders 19 can slide synchronously and in opposite directions along the two second screws 22 through the action of the threaded structure. This allows the two base plates 13 to slide synchronously and in opposite directions on the processing table 1, which facilitates temporary adjustment of the distance between the two support shafts 17 and makes it convenient for this structure to support steel pipe workpieces of different diameters.

[0031] In this embodiment, both the outer end of the third screw 24 and the outer end of the rotating shaft 21 are provided with a toggle block, so that the rotating shaft 21 and the third screw 24 are easy to operate.

[0032] In this embodiment, both the first motor 9 and the second motor 11 can be servo motors.

[0033] The lack of a guiding structure between the baffle 3 and the processing table 1 will affect the stability of the baffle 3 when sliding. The processing table 1 is provided with a guide groove 4, and the lower end of the baffle 3 is provided with a guide block that slides with the guide groove 4. The cross-section of the guide groove 4 is T-shaped. When the baffle 3 slides, the guide block can slide in the guide groove 4, which can provide a guiding structure between the baffle 3 and the processing table 1 and ensure the stability of the baffle 3 when sliding.
